Concatenate list elements into a number in Mathematica -


i trying generate circular prime numbers in mathematica 8.
circular prime number number such rotations of digits prime

eg. 197 circular because 971, , 719, primal too.

now, in order test if prime number circular, generate rotations. follows:

p = integerdigits[197]; table[rotateleft[p, n], {n, length[p]}]

which consequently returns

{{9, 7, 1}, {7, 1, 9}, {1, 9, 7}}

however stuck. grab elements of each inner list , concatenate them in sequential order output becomes this

{971, 719, 197}

so can test if rotations satisfy primeq[].

while on 1 hand have done looping through list, seems me if there better way not realizing.

fromdigits you're looking for.

fromdigits /@ {{9, 7, 1}, {7, 1, 9}, {1, 9, 7}} {971, 719, 197}
